Cardiac resynchronization therapy (CRT) using left- (LV) or biventricular pacing is widely applied in selected heart failure patients. However, transvenous LV-lead placement into coronary sinus (CS) branches can be challenging. A 77-year-old female patient with New York Heart Association class III symptoms due to dilated cardiomyopathy [LV ejection fraction (LVEF): 10%, QRS-duration: 150 ms], d...

A total of 32 (3.6%) patients of 880 undergoing coronary angioplasty during a nine year period at one hospital had extensive dissection (defined as a dissection extending beyond the limits of the dilated angioplasty balloon) in the coronary artery in which the angioplasty procedure was performed. Two (6.25%) of the 32 patients (both of whom were undergoing angioplasty because of unstable angina...

Background: Central vein stenosis (CVS) is common in hemodialysis patients and caused by the implantation of cardiac intravascular devices, venous access, limited vascular access. The effect may develop until an arteriovenous fistula (AVF) or graft established ipsilateral arm forearm for hemodialysis. Arm edema, significant dilatation, recurring infections are complications having Case Illustra...

Introduction: Coronary angiography and angioplasty procedures lead to significant radiation exposure of patients. In the current study, the average radiation dose to patients during angiography in the Angiography Department of Shahid-Madani Hospital was determined. Materials and Methods: An image intensifier based angiography unit (Philips BH 3000) was used for angiography procedures. The accur...

To examine the cardiovascular adaptations and functional capacity (6 min walk test, rate of perceived exertion, resting heart rate, maximal systolic diastolic blood pressure, mean arterial pressure) by giving Aerobic Exercises in Post Percutaneous Transluminal Coronary Angioplasty patients. The need for study is to know efficiency aerobic exercises post percutaneous transluminal coronary angiop...

INTRODUCTION Pulmonary vein stenosis (PVS) is a potential complication of pulmonary vein isolation (PVI) using radiofrequency energy. The aim of our study was the evaluation of the severity and long-term outcome of primary angioplasty and angioplasty with pulmonary vein stenting for PVS. METHODS AND RESULTS Twelve patients with 15 PVS (greater than 70% stenosis) were prospectively evaluated. ...

Coronary dissection occurs frequently and in several degrees during coronary angioplasty, which is one of the mechanisms for increasing the lumen diameter of a vessel. However the length of the dissection may affect the procedure, becoming the most frequent cause of total occlusion after coronary angioplasty. We report here a case of extensive dissection that occurred during the coronary angiop...

case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...

Operator radiation exposure during percutaneous transluminal coronary angioplasty as compared with that during routine coronary angiography is unknown. Therefore, cumulative radiation exposure at operator eye level was measured in two physicians (operators 1 and 2) during performance of coronary angioplasty and routine coronary angiography. The physicians participated together during angioplast...
